HDK® H15

HDK® H15 is a synthetic, hydrophobic, amorphous silica produced via flame hydrolysis. It is a white colloidal powder of high purity. HDK® H15 is commonly utilized as a thickening and thixotropic agent in coatings, printing inks, adhesives, cosmetics, and other applications. Additionally, it serves as a reinforcing filler in elastomers, particularly silicone elastomers. Moreover, HDK® H15 functions as a free flow additive in the production of technical powders.
